The Rag'Tall are one of the more facinating creatures on Rag. They evolved to land creatures at one point of their evolution and then returned to the sea much like dolphins and whales. They still breath air and live close to the surface of the sea. Their diet exists out of mostly fish and fruits that grow under the sea.
They are fast swimmers when they use all five fins in unison to escape most dangers.
The Rag'Tall are quite intelligent and have passed the Rag'Kor their self awarness test. They werent the first creatures to do so but they did. This gives the creature rights much like a person. They are protected from hunting and have basic rights.
